5632:Rikka with Array

题目描述
As we know, Rikka is poor at math. Yuta is worrying about this situation, so he gives Rikka some math tasks to practice. There is one of them:

Yuta has an array $A$ of length $n$,and the $i$th element of $A$ is equal to the sum of all digits of $i$ in binary representation. For example,$A[1]=1, A[3]=2, A[10]=2$.

Now, Yuta wants to know the number of the pairs $(i,j)(1 \leq i < j \leq n)$ which satisfy $A[i] > A[j]$.

It is too difficult for Rikka. Can you help her?
输入解释
The first line contains a number $T(T \leq 10)$——The number of the testcases.

For each testcase, the first line contains a number $n(n \leq 10^{300})$.
输出解释
For each testcase, print a single number. The answer may be very large, so you only need to print the answer modulo 998244353.
输入样例
1
10
输出样例
7

When $n=10$, $A$ is equal to $1,1,2,1,2,2,3,1,2,2$.

So the answer is $7$.
